SMC Reset needed for every boot, sleep wake and completely turned off

Hello,

My MacBook Pro A1708 won’t wake up from sleep after closing and opening up the lid. The Keyboard lights up and the touchpad clicks but the screen stays black. The only way to get it to show a picture is to reset the smc. (I actually don’t have to hold the keys for 10s). If I do so it goes straight to the login screen without the booting apple logo.

When I shut it down completely it won’t start without resetting the smc. (I have to hold the keys for 10s)

I’ve already tried resetting the nvram and disabling hibernate and sleep mode. I’ve reinstalled macOS.

When I connect the charger the problem seems to occur not that often but still sometimes.

Battery has 600 cycles and seems to be in normal condition according to apples system report.

What could cause this problem?

Thank you!

Hi,

Here’s a picture of coconutBattery:

Im going to disconnect the battery cable and see if the problem still occurs.

Hi,

So the problem still occurs even with the battery completely disconnected from the board and the MacBook only running on the external power supply.

One thing I noticed is that sometimes when the screen stays black the backlight of the screen just didn't light up. With the help of a flashlight I can log in without problems. Sometimes I can't see anything on the screen even with a flashlight.

Plugging in an external Monitor as well as the power adapter sometimes helps.

@danj The problem still occurs even with battery percentage of 100%. It seems that the battery percentage has no influence.
